Developed by the Oxfordshire-based engineering company that operates alongside the Atlassian Williams Formula 1 Team, the ES10M can be configured for yachts from around 50 metres to over 100 metres in length. The scalable battery system supports hybrid propulsion, battery-powered hotel loads and fully electric applications for tenders, chase boats and support vessels.
Why is Formula 1 technology being used in superyachts?
Williams Grand Prix Technologies is applying the battery expertise developed through Formula 1 to meet growing demand for hybrid propulsion and more efficient onboard energy systems.
As superyacht builders and refit specialists seek to improve energy efficiency and adopt alternative propulsion technologies, this is the ideal time to bring our extensive battery systems expertise from the Atlassian Williams F1 Team to the marine sector."

What yachts can the ES10M battery support?
The ES10M has a modular design that can be tailored to different vessel sizes, from yachts around 50 metres to superyachts exceeding 100 metres. Each module stores 9.8kWh of energy, while complete systems range from 39kWh to 4.2MWh, allowing the battery to support hybrid propulsion, hotel loads or fully electric applications depending on the vessel's requirements.
How does the ES10M improve safety?
Safety is built around a layered architecture that uses thermal protection materials, integrated gas management and an advanced battery management system. Using physics-informed machine learning, the software monitors battery cells in real time, predicts load behaviour and identifies potential faults before they occur, while remote diagnostics allow operators to monitor the system offsite. The battery modules are IP67 rated, with Lloyd's Register class approval currently in progress.
Why does the ES10M matter for the superyacht industry?
As more builders adopt hybrid propulsion and alternative energy systems, scalable battery technology is becoming an increasingly important part of both new-build and refit projects. By adapting Formula 1 battery expertise for marine applications, Williams Grand Prix Technologies is entering a rapidly expanding sector with a system designed to support a broad range of motor yacht energy requirements.
